The Delta Force (1st Special Forces Operational Detachment-Delta), is a U.S. Army unit used for hostage rescue and counterterrorism, as well as direct action and reconnaissance against high value targets.elta Force was formed after numerous, well-publicized terrorist incidents in the 1970s. These incidents led the U.S. government to develop a full-time counter-terrorism unit. Key military and government figures had already been briefed on a model for this type of unit in the early 1960s.
Delta Scientific, a manufacturer of counter-terrorist vehicle control systems used in the United States and internationally, announced that over 200 government officials and security professionals in the Birmingham, Alabama, area attended demonstrations of Delta's wide line of anti-terrorism vehicle barriers, bollards, crash-rated gates and other equipment, including new products, on November 2, from 10 am to 4 pm at Regions Field Stadium in Birmingham.
